REFERENCE INFORMATION The fuel pressure should always be greater than 3 psi (21 kPa). If you get about the same pressure with the 2 transducers, then you have a fuel system problem. Remove fuel pressure transducer (para. 4-30). Make sure the STE/ICE-R is powered by a W5 cable. You will have to decide if Test 24 gave the wrong result. If Test 24 gave a substantially different result than Test 49, answer NO to this question. NOTE VEHICLE DCA FAULTY. Use the STEIICE-R in the TK mode for the rest of your testing. See the chart on the foldout page for a way to run the rest of the DCA tests in the TK mode. Have DS maintenance repair the DCA when you’re finished.
